VENTED CIGARETTE HOLDER Filed March 2, 1964 11 J A/ /z W j QMWZQE UnitedStates Patent 3,265,074 VENTED CIGARETTE HOLDER Francis W. Davis, 90Common St., Belmont, Mass. Filed Mar. 2, 1964, Ser. No. 348,483 1 Claim.(Cl. 131198) This invention relates to a cigarette holder which isvented to mix a controlled proportion of air with the smoke Which isdrawn through the holder. Several advantages result from such a dilutionof the smoke from the cigarette in the holder. The actual quantity ofthe smoke drawn into the mouth is reduced, thus lessening the toxiceifect of the smoke. The air has a cooling eflect on the smoke, with theresult that the smoke mixture drawn into the mouth is lighter andpleasanter than undiluted smoke. For health reasons, physicians oftenadvise patients to cut down on their smoking. Where a certain number ofcigarettes per day has become a fixed habit, such a reduction is oftendiflicult to accomplish. By mixing the smoke with air, the desiredreduction can be obtained without otherwise changing the establishedsmoking habit. Attempts to realize these objectives have resulted in anumber of patents showing various devices.

In ventilating smoke firom a cigarette, it is desirable that the degreeof dilution be constant and that it be ad justable to suit difierentrequirements. An object of the present invention is to provide acigarette holder which can be easily made by a small modification of aholder now on the market, the modified holder being readily adjustableto dilute the smoke by different constant amounts. This is done by theprovision of a collar rotatively adjustable to move any one of a numberof vent holes of different diameters into operative position and to lockthe collar in any adjusted position.

For a more complete understanding of the invention, references may behad to the following description thereof, and to the drawing, of whichFIGURE 1 is a perspective view of a vented cigarette holder embodyingthe invention;

FIGURE 2 is an exploded elevational view of the same on a larger scale,both ends being broken off;

FIGURE 3 is a fragmentary elevation, on a still larger scale, of theparts shown in FIGURE 2, partly broken away to show in section;

FIGURE 4 is a section on the line 4-4 of FIGURE 3;

'FIGURE 5 is a perspective view of the collar shown in FIGURE 4; and

FIGURE 6 is an elevational view, similar to FIGURE 3, of a modified formof the invention.

The vented holder illustrated on the drawing can be easily andeconomically made by minor alterations in a holder now on the market.That' holder consists of two parts screw-threaded together. One part isthe mouthpiece having a forward portion of reduced diameter with a fewscrew threads on the outer surface. The other part is a tubular memberadapted to receive an end of a cigarette and provided with a fewinterior screw threads to engage the threads on the mouth-piece part. Asmodified according .to the invention, the mouth-piece part 10 has aportion 12 of reduced diameter forming a shoulder 14 spaced from thescrew threads 16. The tubular member -18 with the interior threads 20 isnot changed. The member 18 and mouth-piece part 10 have the usual duct22 through which smoke is drawn from the cigarette into 3,265,074Patented August 9, 1966 the mouth. A radial hole 24 extends outward fromthe duct 22 through the wall of the reduced portion 12 of themouth-piece part. A thin sleeve 26 is fitted on the reduced portion 12and is rotatable thereon. The sleeve is preferably provided with aknurled flange 28 to fa cilitate rotative adjustment. A series of holesof graduated sizes are provided in the wall of the sleeve. Four suchholes 30, 3-2, 34, 36 are shown but the number of holes may be more orless as desired. In one embodiment of the invention, the four holes aremade by drills of the following sizes:

piece part is larger than any of the holes through the sleeve. Rotativeadjustment of the sleeve brings any of the holes in the sleeve intoregistration with the hole 24 so that .a vent of definite size is had.As indicated in FIGURE 3, When the holder is assembled, the tubularmember 18 only presses against one end of the sleeve 26 and presses theother end of the sleeve into binding contact with the shoulder 14, thustrictiona'lly locking the sleeve against rotation regardless of anysmall variations there may be in the length of sleeves 26 whenmanufacture-d in quantity. The sleeve can be easily released forrotative adjustment by slightly unscrewing the tubular member '18.

The form of the invention shown in FIGURE 6 is like that shown in FIGURE3 except that the mouthpiece part is in two parts '10 and 12,screwsthreaded together, instead of in one part 10 as shown in FIG- URE3. A sleeve 26 with a knurled flange 28' is nearly identical with thesleeve 26 and is locked against rotative movement by being pressedbetween shoulders on the parts 18 and 1 2'.

I claim:

A vented cigarette holder comprising a mouth-piece having a tubular endportion of reduced diameter forming a shoulder, said reduced end portionhaving a screwthreaded part spaced from said shoulder and a radial holethrough the wall thereof between the threaded part and the shoulder, asleeve rotatably fittedon said reduced portion between said shoulder andsaid threaded part, said sleeve having a knurled flange and a series ofholes of various sizes selectively registrable with thehole through saidwall be rotation of the sleeve, and a tubular cigarette-receiving partin threaded engagement on said threaded part, the end of saidcigarette-receiving part bearing only against an end of said sleeve topress the other end of the sleeve into binding engagement with saidshoulder to lock the sleeve against rotation.
